I've recently discovered a good blog, based around all things S.E. London, called Transpontine. I had to look up what the word meant (sorry!) but was happy to find it aptly means:
Of, pertaining to, or situated on the far side of a bridge.
Of, or pertaining to the sensational melodramas presented on the south side of the Thames in the 19th century or earlier.
They were kind enough to run a little piece about my work. Which was nice.
